Etude des inclusions végétales dans les archéomatériaux argileux, par imprégnation de polymères
International audience; Cette application, en cours de perfectionnement, est destinée à l’étude de matériaux archéologiques contenant deséléments végétaux, comme des poteries ou des matériaux de construction. Elle devrait être utile aux archéobotanistes et leur fournir une nouvelle source de matériel à exploiter. Plus largement, cette technique est destinée à fournir de nouvelles sources d’étude pour la technologie des matériaux, la gestion des matières premières et le traitement des produits alimentaires.
Étude d'inclusions végétales dans des tessons de poterie ou des matériaux de construction
Vegetal inclusions embedded in clayey materials (cob, ceramic, mudbrick) are investigated by using impregnation of the porous material with a fluorescent polymer. The micro-casting of the porosity is exploited by following two ways. Sections of the treated samples are examined under UV-light, showing vegetal structures amenable to a botanical identification and quantification. Moreover, micro-casts embedded in the mineral matrix have been successfully sorted. This new application is a tool to study archaeological samples previously not amenable to the work of archaeobotanists and to expand their field of investigation.
Quantifying cereal-reaping microwear on flint tools : an experimental approach
International audience; From the earliest Neolithic in the Near East to the last Chalcolithic cultures in Western Europe, certain flint tools have been used as sickles to harvest cereals. Such harvesting tools can be identified through use-wear analyses, because cutting herbaceous plants produces specific wear-traces on the working edge of flint blades. The aim of this work is to explore harvesting-driven microwear variability and, more particularly, intensity of use as a governing factor. To achieve this objective, an experiment was designed consisting in the production of flint replicas to be used as harvesting tools, in various controlled conditions. A simple, cost-effective method of qu…
